What are PUR Hot Melt Adhesives?

PUR hot melt adhesives are a type of adhesive that uses polyurethane as the primary bonding agent. They are typically applied in a molten state using a hot melt glue gun and cure as they react with moisture in the air or on the substrate surface. This curing process creates a strong and durable bond that is resistant to water, heat, and chemicals. Check out our complete guide comparing Traditional Hot Melt to PUR Polyurethane Adhesives

PUR hot melt adhesives work by reacting with moisture in the air or on the substrate surface. The adhesive is applied in a molten state using a hot melt glue gun and then solidifies as it cures or hardens. During the curing process, the adhesive reacts with moisture in the air or on the substrate surface, which triggers a chemical reaction that forms a strong and durable bond.

Advantages of PUR Hot Melt Adhesives:

  • Strong Bonding Strength: PUR hot melt adhesives offer excellent bonding strength to a variety of substrates, including metals, plastics, and wood.
  • Water and Moisture Resistance: The cured bond created by PUR hot melt adhesives is resistant to water and moisture, making them ideal for outdoor applications or environments with high humidity.
  • Long Open Time: PUR hot melt adhesives have a long open time, which allows for easy handling and positioning of the adhesive before it cures.
  • Low Application Temperature: PUR hot melt adhesives can be applied at a lower temperature than traditional hot melt adhesives, which reduces the risk of heat damage to the substrate material.

Comparing Waterproof Glues: Advantages of PUR Hot Melt Adhesives Over PVA and Epoxy

When it comes to waterproof glue, PVA and epoxy are two popular options that are often compared to PUR hot melt adhesives. Check out our complete guide: Exploring Waterproof Glues: A Comparative Analysis. Here are some advantages and disadvantages of PUR hot melt adhesives compared to these other types of waterproof glue:

PVA Waterproof Glue:

  • Advantages: PVA glue is easy to use, dries clear, and is widely available. It is also relatively affordable and is commonly used in woodworking and crafts.
  • Disadvantages: PVA glue is not as strong or durable as PUR hot melt adhesive, and it is not recommended for applications that require resistance to moisture or chemicals.


  • Advantages: Epoxy is a very strong adhesive and can be used on a variety of substrates. It is also highly resistant to water and chemicals and can create a very strong bond.
  • Disadvantages: Epoxy can be difficult to work with, requires careful mixing, and can take longer to cure than PUR hot melt adhesive. It can also be more expensive than other types of waterproof glue.

PUR Hot Melt Adhesive:

  • Advantages: PUR hot melt adhesive creates strong and durable bonds that are highly resistant to water and chemicals. It is also fast-curing and versatile, making it suitable for a wide range of applications across industries.
  • Disadvantages: PUR hot melt adhesive is difficult to remove once cured.

Overall, while PVA and epoxy have their own unique advantages, PUR hot melt adhesive offers a combination of strength, versatility, and resistance to water and chemicals that make it a superior choice for many applications. However, it is important to consider the specific needs of your application and choose the adhesive that is best suited for your project, contact an adhesive expert at from Hotmelt.com today!

Make sure to check out our video: Best Practices When Working With PUR Polyurethane Hto Melt Adhesives. To ensure the best performance from your PUR hot melt adhesive, consider these tips when choosing the right adhesive for your specific application:

  1. Identify your substrate: Determine the type of substrate you will be bonding, and consider factors such as its surface characteristics, porosity, and strength.
  2. Determine your application requirements: Consider the environmental conditions the adhesive will be exposed to, such as temperature and humidity, as well as any specific performance requirements such as bond strength, flexibility, or chemical resistance.
  3. Choose the right adhesive: Select an adhesive that is formulated for your specific application requirements and substrate. Different adhesives have different formulations and properties that make them suitable for different applications.
  4. Choose the right equipment: Ensure that you have the appropriate equipment for applying the adhesive. This may include a hot melt adhesive system, application nozzles, and dispensing guns.
  5. Test the adhesive: Before starting a large-scale project, it is important to test the adhesive on a small scale to ensure that it will perform as expected. This can help you avoid costly mistakes and ensure the success of your project.
